Getting a dog!!!!??? 🐾🐾🐶🐾🐾 OPINIONS ( have children)

hi everyone so me and my partner are going to look at a dog this weekend that we have fallen in love with (in pictures) it is a German shepherd. I have been brought up with them my whole life since crawling as a baby I was just wondering what your opinions are as I have an almost 17 month old who is obviously walking ect but young and I am also pregnant currently 26 weeks the dog will be 13 weeks old when I go see it you usually get them at 8 weeks old but he / she is a little older depending on what one I choose ! I was wondering what your opinions are. obviously I would never leave my kids alone and unattended with a dog and it will have space from the kids but interested in opinions as some people are so against it.
